The invention discloses a ship manipulation forecast database updating method based on six-degree-of-freedom attitude data of a real ship. The method specifically comprises the following steps: constructing an initial ship manipulation forecast database; perfecting and complementing the initial ship manipulation forecast database; and updating and optimizing the perfected and complemented ship control forecast database. According to the method, the defects that an existing method is not high in ship control forecasting precision, forecasting errors do not have robustness, and forecasting real-time performance is not high are overcome. According to the method, the six-degree-of-freedom attitude data acquired by a real ship can be fully utilized to form a database so as to forecast the ship maneuvering performance. Through collection of six-degree-of-freedom attitude data of a ship in different navigation working conditions, the database is continuously complemented, improved, updated and optimized, so that a ship maneuvering forecasting database which covers the working conditions comprehensively and is continuously updated is obtained, and accurate real-time forecasting of ship maneuvering performance is achieved.
本发明公开了一种基于实船六自由度姿态数据的船舶操纵预报数据库更新方法,该方法具体包括构建初始船舶操纵预报数据库;完善补全所述初始船舶操纵预报数据库;更新优化所述完善补全后的船舶操纵预报数据库。本发明解决了现有方法对船舶操纵预报精度不高、预报误差不具有鲁棒性以及预报实时不强的缺点。本方法能充分利用实船采集的六自由度姿态数据形成数据库,来预报船舶操纵性能。在通过对不同航行工况中船舶六自由度姿态数据的收集,不断对数据库补全完善、更新优化,从而得到一个覆盖工况全面、持续不断更新的船舶操纵预报数据库,达到对船舶操纵性能的精准实时预报。
